Delete Study

delete_study

DestructiveIdempotent

Soft-delete a study and its linked invitations, interviews, and reports from normal reads. Participant links stop working. There is no public restore endpoint. Uploaded assets may have separate retention. Call only when the human explicitly requests deletion of this study.

`study_id`	Yes
`organization_id`	No	Organization for this operation and billing. Use list_organizations to choose an active membership.

A3.9/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is known. The description still earns credit for non-obvious behavior the annotations cannot convey: cascade scope, participant links breaking, no public restore endpoint, and separate asset retention. No contradiction with annotations — 'soft-delete' and 'no restore endpoint' are consistent with destructiveHint=true.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Five short sentences, each carrying distinct information: cascade scope, link breakage, irreversibility, asset caveat, and the human-approval gate. The destructive consequence is front-loaded and there is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

A mutation tool with an output schema present, so return values need no explanation; annotations plus the description together cover safety, irreversibility, and cascade effects. An agent has everything needed to decide and call correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 50%: organization_id is documented in-schema, study_id is an obvious UUID. The description says nothing about either parameter, relying entirely on the schema. Baseline 3 is appropriate since roughly half the parameters are self-evident and half documented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Specific verb (soft-delete) plus resource (study) plus the cascade scope (invitations, interviews, reports). It clearly separates itself from pause_study/stop_study by stating the data is removed 'from normal reads', but it never names an alternative tool such as remove_research_study, so the differentiation is inferential rather than explicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Call only when the human explicitly requests deletion of this study' is a concrete gating condition, effectively a when-not-use rule for autonomous agents. It stops short of naming the correct sibling for softer actions (stop_study, pause_study) or the alternative removal path (remove_research_study), which would have made it a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
